Definitions

  • the tub is made in two pieces of plastic material.
  • a first piece has a first opening for introduction of the basket and a second opening, set opposite to the first opening or on the other side of sad first piece, for access to the basket and for introduction therein of the laundry.
  • a second piece or lid closes the opening for the introduction of the basket after this has been inserted into the aforementioned first piece.
  • Said second piece is usually fixed to the first piece by means of elastic engagement elements or fixing clamps or screws, after positioning of a seal element or gasket in between.
  • FIGS 1 to 6 illustrate a first embodiment of a tub for a washing machine of the top-load type, designated as a whole by the reference number 2.
  • the tub 2 consists essentially of a hollow body made of plastic material, designed to contain a perforated basket 3 with holes 9, as known.
  • the tub 2 also supports a motor 4, which actuates rotation of the basket 3 by means of a pulley 5 connected to the basket 3.
  • the front lid 8A of Figure 4 which is similar to the rear lid 8B of Figure 3, is obviously without the groove 17.
  • Co-moulded or applied to the lid is a chamber 15Z having a pre-defined volume and position.
  • the chamber connects the inside of the tub to an external pressure switch (not shown). With the introduction of water into the tub, the air in the chamber 15Z is compressed, thus causing triggering of a pressure switch that electrically closes the solenoid valve, thereby controlling the entry of water. This cycle controls the amount and level of water necessary for washing.
  • the upper shell 30 is fixed to the lower shell 31 by fastening means comprising a plurality of clamps 40 engaging a rib 42 projecting from the lower shell 31.
  • Clamps 40 are positioned in the vicinity of the open edges of shell 30, particularly the longitudinally oriented edges 41. As shown in particular in Figure 11 and 13, each clamp 40 swings around a hinge line 44 and is provided with a tooth end 46 to engage a corresponding recess 47 of rib 42.
  • Figures 10, 11 show the clamping means in an open position
  • Figures 12, 13 show the clamping means in the closed position.
  • shells 30, 31 have semi-circular projections 45, 45A provided with a hole to house bearings 80 to support hubs 88 of the basket 3, as it will be explained in more detail in the following of the description.
  • Projections 45, 45A match corresponding semi-circular recesses in the corresponding shell.
  • each bearing 80 is embedded in a groove 81 of the tub 2, so as to receive a hub 88 of the basket 3.
  • the bearing 80 is made as one piece with the tub 2, the latter being made directly “around" the bearing, for example by means of moulding, namely by suitably positioning the bearing in the mould where the tub is made by injection or blow moulding.
  • moulding of the tub 2 is made by embedding at least one bearing 80 for a rotary support of the basket 3.
  • the tub of the invention is a multifunctional tub insofar as it exploits several functions besides that of providing a sealed chamber for hosting the basket, including the function of providing a built-in counterweight and the function of incorporating built-in bearings.
  • each lid/counterweight may be made up of just two components, i.e., a component made of plastic material obtained in a single piece with a component made of conglomerate, said components being fixed together.
  • all the items may be replaced by technically equivalent elements.
